Former Lebanese premier returns to mark the 10th anniversary of his father's assassination

The massive explosion that tore through his convoy on the Beirut seaside 10 years ago sent a tremor across the region and unleashed a popular uprising that briefly united the Lebanese and ejected Syrian troops from the country. But a decade later, and despite millions of dollars spent, justice remains elusive in a case that has been overshadowed by more recent turmoil. (AP Photo/Hussein Malla)

BEIRUT – Former Lebanese Prime Minister Saad Hariri has returned to Lebanon to mark the 10th anniversary of his father's assassination, a slaying that sharply divided Lebanon.

Rafik Hariri was killed with 21 others in massive truck bomb on a Beirut seaside road on Feb. 14, 2005.

Saturday's visit marks Saad Hariri's second return to Lebanon after four years in self-imposed exile. Hariri visited Lebanon briefly in August. He left Lebanon in January 2011 after his government was brought down by Hezbollah and its allies.

Hariri is scheduled to give a speech later Saturday at a ceremony making the assassination.

Hariri's father was Lebanon's most prominent Sunni politician. A United Nations-backed tribunal is trying in absentia five members of the militant Hezbollah group, the country's most powerful Shiite faction, for the bombing.
